What is the difference between ponds, lakes, rivers, seas, and oceans

The video explains the differences between oceans, seas, and billabongs.

Summary of the video:
- Oceans: The largest bodies of saltwater on Earth, covering most of the planet’s surface.
- Seas: Smaller bodies of saltwater, often partially enclosed by land and connected to an ocean.
- Billabong: An Australian term for a small, isolated body of water, usually formed when a river changes course, leaving behind a still water area.

The video also mentions that while Australia’s national anthem states the country is *"girt by sea"*, in reality, it is surrounded by the ocean.
